-With the LED deck and a Crazyflie 2.x, we are able to make real pieces of art, like in the light paintings in this [[https://​www.bitcraze.io/​2019/​03/​lighthouse-painting/​|blog post]] or even the [[https://​www.bitcraze.io/​2019/​03/​drawing-images-with-crazyflie-and-bitcraze-at-icra-2019/​| Mona lisa]].

 __How about using the LED-deck in the combination with the [[https://​www.bitcraze.io/​flow-deck-v2/​|Flow deck v2]]?__ A while ago we managed to do this by drilling a couple of holes in the LED deck in this [[https://​www.hackster.io/​krichardsson/​light-paint-with-a-drone-d050af|hackster project]]. However, if you are fine with putting the LED deck on the top, there might be an easier way to achieve this combination. __How about using the LED-deck in the combination with the [[https://​www.bitcraze.io/​flow-deck-v2/​|Flow deck v2]]?__ A while ago we managed to do this by drilling a couple of holes in the LED deck in this [[https://​www.hackster.io/​krichardsson/​light-paint-with-a-drone-d050af|hackster project]].

 +What we are essentially doing, is that we are flipping the pin-layout of the LED deck so that it is compatible to be put on the top of the Crazyflie.
 +
 +The image below shows how you should solder the wiring. The **Gnd** (ground),** IO2**, **OW** (deck single wire memory), and **VCOM** (power supply). Please check out this [[projects:​crazyflie2:​expansionboards:​index|page]] to familiarize yourself with the pin-outs of the expansion decks. ​

 +We did not connect **IO3** on purpose since the Flow deck v2 is already using this, or else the LED deck and Flow deck will conflict with each other'​s communication with the Crazyflie. However, the LED deck should work as well without the IO3 connected

 +The battery holder deck can be glued on the LED-deck or attached with some tape.The wiring and soldering are done a bit crude for now to clearly show how to do this, however if you would like the wiring not to be shown as clearly as it is here, this should be easy to fix with thinner wires and basic soldering skills. =)
 +
 +__Please pay attention to that the orientation of the LED deck is now different__. We put the battery holder on the side to prevent any connections to short with the LED deck, but now you would need to indicate the new '​front'​ of the LED deck. On the bottom left picture we show it with a sticker.

 +We tested the converted LED deck with the Flow deck v2 with the CFclient and we are still receiving the values and parameters from both the deck drivers. At the moment of writing **we haven'​t test-flown this configuration yet**, but we hope to do it soon for another long exposure light painting!
